The following events are the most relevant performance data:
• paging
• dropped voice call
• dropped message
• handover
• RFP-channel occupation
• S-channel occupation
• B-channel occupation
• degradation of service
• grade of page failures
• grade of page retries
• grade of page rejects
Paging
Paging is the process of broadcasting a message from an RFP to one or more PPs. Paging
messages are used to alert a PP (a call setup attempt). The paging message contains the
system information and the identifier of a PP. A PP enters the alert phase when it recognizes
its own identifier.
The following events (performance data) are associated with paging messages:
• Request: number of call setup attempts
• Retries: number of call setup attempts after the PP did not respond on a page request
• Failure: after a number of page retries (default is two attempts), the call setup attempt is
aborted (that is, the paging procedure failed)
• Reject: the PP responds to the request, but rejects the call setup attempt
Dropped voice call
A dropped voice call occurs when the PP loses the connection with the RFP. The PP is no
longer able to make or receive a call.
A dropped call can occur during either of the following phases:
• Active phase: the PP loses the synchronization with the RFP with a call in progress
• Call setup phase: the PP loses the synchronization with the RFP, but there is no call in
progress
